Specialty: Analytical Chemistry, Chemical Education, Archaeological Chemistry, Forensics 

Biography: Dr. Braun, a native of McPherson, KS, has been a chemistry professor since 2007. In 2018, he joined the faculty at VMI where he teaches courses in general chemistry, analytical chemistry, instrumentation, and archaeological chemistry. He earned a B.A. in anthropology and a B.S. in chemistry before obtaining his Ph.D. at the University of Arizona in the groups of Dr. Craig Aspinwall and Dr. Joseph Perry. His graduate research focused on the characterization and application of multiphoton chromophores in micro and nanolithography and on enhancing the electrophoretic detection of neurotransmitters using Hadamard transforms. This was followed by a post-doctoral research position in Dr. J. Michael Ramsey’s group at the University of North Carolina-Chapel Hill centered on DNA sequencing using micro and nanofluidics. When not working with cadets, Dr. Braun enjoys exploring the region’s vast natural and historical sites with his wife and three daughters. 

Academic Interests: Research in the Braun group is divided between three areas: archaeological chemistry and the analysis of archaeological pottery lipid residues; the degradation of inks and pigments as applied to forensic document analysis; and chemical education as it pertains to the development of novel, context-based curricula/resources and the implementation of pedagogical best practice. Additional research interests include the synthesis and analysis of biofuels, characterization of hazardous chemicals used in museums and taxidermy, and signal multiplexing in separation science.

Specialty: Physical Chemistry &Synthesis of Inorganic Complexes for Applications in Electrocatalysis and Renewable Energy

Daniel Harrison is a 2005 VMI chemistry graduate. He was awarded his Ph.D. at the University of Virginia where he studied the ability of inorganic compounds to modify the standard organic chemistry of aromatic molecules. Many of the novel compounds he synthesized are at the National Institutes of Health: Molecular Library for Small Molecule Repository to evaluate their biological activity. Daniel continued his research career as a Post-Doctoral research associate with Thomas J. Meyer at the University of North Carolina at Chapel Hill’s Energy Frontier Research Center: “Solar Fuels.” There he studied the catalytic conversion of H₂O and CO₂ into usable fuels for applications in renewable energy technology. Daniel returned to VMI in January 2013 and is currently teaching Physical Chemistry. At VMI, his research efforts focus on utilizing electrochemical methods to analyze inorganic molecules that his students synthesize, in order to determine their ability to produce usable combustible fuels from electricity. His research is a part of a larger global effort to produce renewable fuels and help develop a carbon neutral economy. Daniel originally became interested in science because of his fascination with colors, fireworks, and a desire to understand and explain our physical surroundings with concrete descriptions.

Specialty: Analytical Chemistry and Detection of Small Molecules Using Organic Phases

Dr Quevedo is an analytical chemist interested in the detection of small molecules. Small molecules, including pollutants, toxins and opioids, are extremely challenging to detect, both because of their relatively small size and their similarity to one another, making specificity challenging. Dr. Quevedo is using hydrogels, cross-linked polymers which swell in water solutions, as a way of enhancing the signal and specificity of small molecule detection.  Her work focuses not only on synthesizing and testing hydrogel detection mechanisms, but also understanding why hydrogels behave differently depending on their environment as well as alternative detection methods to enhance signals from the hydrogel. Dr. Quevedo is also committed to further integrating current technology into the chemistry curriculum, with a focus on biotechnological applications.

Prior to coming to VMI, Dr. Quevedo completed her bachelors at Harvey Mudd College, with a focus on small molecule synthesis, and her PhD under Professor Ryan Bailey at the University of Michigan Ann Arbor, focusing on developing microfluidic organic phases for improved small molecule detection.

Dr. Smith is an organic chemist with research interests in natural products chemistry and synthetic methodology. One aspect of this work is the synthesis of novel nitrogen-containing natural products; particularly indole alkaloids from sea sponges and pyrazole alkaloids from traditional folklore plants. Another aspect of research is the use of vinamidinium salts as synthetic intermediates to construct nitrogen-containing heterocycles. Prior to coming to VMI, Dr. Smith was a postdoctoral chemist at Research Triangle Institute in North Carolina working on a project to chemically inactivate nerve agents.
